What is a number bond to 20?

We can look at number bonds to 20 as pairs of numbers with a total of 20.

However, knowing your number bonds to 20 is more than just being able to quickly recite pairs that have a total of 20.

We would also expect children to know all the facts related to the pair of numbers that have a total of 20.

In other words:

  • If we know that 13 + 7 = 20, we should also know
  • 7 + 13 = 20
  • 20 - 13 = 7
  • 20 - 7 = 13
  • And if we switch the equation on either side of the equals sign, we could add to this...
  • 20 = 13 + 7
  • 20 = 7 + 13
  • 7 = 20 - 13
  • 13 = 20 - 7

So there would be a total of 8 facts for every number bond fact that we would want children to be able to find!

The sheets below will help you child to learn their number bonds to 20 and accompanying facts!
